Singer Whitney Houston reportedly died because she mixed prescription drugs with alcohol.
An autopsy on the 48-year-old singer, who was found dead in the bathroom of her room at the Beverly Hilton Hotel Saturday, has been completed and Los Angeles County Coroner officials have told her relatives that she did not drown.
According to the sources, the coroner did not find enough water in Whitney's lungs to suggest she died in the bath, but they believe her death was a result of the combination of alcohol, Xanax and other prescription drugs she had taken, reports TMZ.com.
However, her autopsy results wouldn't be released until police investigation is complete.
"The Beverly Hills Police Department has requested the Coroner's Office to put the results on a 'security hold' because it could hamper their ongoing investigation," a source told RadarOnline.com.
